Description

31) ATP contains both phosphoester and phosphoanhydride linkages.

ANS : TRUE

Page Ref:Section 3 32) A phosphodiester linkage in DNA contains two phosphorous atoms.

ANS : FALSE

Page Ref:Section 3 33) Lipids aggregate to form bilayers because some lipid molecules are hydrophobic and other lipid molecules are hydrophilic.

ANS : FALSE

Page Ref:Section 3 34) Thermodynamics and its laws are obeyed by living cells.

ANS : TRUE

Page Ref:Section 4 35) The tendency of a metabolic reaction to proceed is due to the free energy of both the reactantsand products as well as the change in randomness of that reaction.

ANS : TRUE

Page Ref:Section 4 36) Biochemical reactions are more likely to proceed if the reaction has an increase in enthalpy ( △H) and a decrease in entropy (△S).

ANS : FALSE

Page Ref:Section 4 37) All prokaryotic cells are about 1/10 the size of an average eukaryotic cell or smaller.

ANS : FALSE

Page Ref:Section 5 38) All cells have kept the same general patterns of metabolism, a very similar genetic code and the same monomers or residues.

ANS : TRUE

Page Ref:Section 5 39) Eukaryotes include plants, animals and bacteria.

ANS : FALSE
